Just started having a problem receiving calls with Ooma Telo. We have Ooma Premier and ported our old number. Also kept the temporary number Ooma provided. When people call our old ported number (which we want as our main number) the calls go directly to voicemail. These are not annonymous calls or numbers on our blacklist. These are calls from people who call all the time. We also have our numbers forwarded to a cell phone. When the cell phone is on, the ported number rings and we can answer it. When the cell phone is off, the ported number sends calls to voicemail. We do not have voicemail set up and use an answering machine. We advised Ooma and they said they disabled the voicemail feature but obviously this is not the case. Any suggestions?
